MECHANISM FOR EXERTING PRESSURE.

SPECIFICATION forming part of Letters Patent No. 718,621, dated. January20, 1903.

Application filed February 24. 1902. Serial No. 95,204. (No model.)

To all whom it may concern:

Be it known that I, EDUARD GUENTHER, a citizen of the United States, anda resident of WVest New York, county of Hudson, and State of New Jersey,have invented a new and Improved Mechanism for Exerting Pressure, ofwhich the following is a full, clear, and exact description. v

My invention relates to mechanism for exerting pressure, and isapplicable to devices varying considerably in function, its purposebeing to provide a very simple and powerful mechanism for exertingpressure upon gaseous, liquid, or even solid bodies. The pressure may beapplied either for the purpose of propelling said bodies or, making useof the reaction principle, for propelling the structure, such as a shipor air-ship, which carries said mechanism, as well as for many otherpurposes, some of which will be indicated hereinafter.

To facilitate a clear understanding of my invention, I have hereuntoappended two sheets of drawings, in which Figure 1 is a longitudinalsectional elevation on line 1 1 of Fig. 2, showing one form of mechanismfor carrying out my invention. Fig. 2 is a cross-section thereof on line2 2 of Fig. 1. Figs. 3 to 6 are diagrammatic longitudinal sectionalelevations illustrating the I operation of the device shown in Figs. 1and 2. Figs. 7 to 10 are similar views of another form of my invention.Fig. 11 is a cross-sectional elevation of the mechanism shown in Figs. 7to 10. Fig. 12 is a longitudinal sectional elevation showing theapplication of my invention to the propulsion of a marine vessel.

I desire it to be clearly understood that while I have shown specificmechanism for effecting the result in viewit is my intention to protectthe features of my invention as broadly as the state of the art willpermit, and the novelty of my improved apparatus will be carefullydefined in the appended claims.

As shown in Figs. 1 and 2, the invention comprises as its principalelements three partsviz., a conduit for the medium (fluid or solid) onwhich pressure is to be exerted, a pressure-exerting member arranged insaid conduit, and mechanism for imparting a poculiar oscillating motionto this member, as will be set forth presently.

The conduit or casing in the particular instance shown consists of atubular body A of rectangular cross-section and open at both ends, oneof which may serve as the inlet and the other as the outlet. This bodyis represented as provided with a downward extension comprising parallellongitudinal walls A A between which may be located a fillingpiece Aspaced from the wall or plate A so as to leave a slot or narrow chamberA between them. As shown in Fig. 1, this chamher is open toward the tubeor conduit A, but is otherwise closed. The conduit has a top A and abottom A extending to the wall A the chamber A being located centrallywith respect to the side Walls of the tube or conduit A.

Within the conduit extends longitudinally a pressure-exerting member inthe nature of a plate B, the ends of this member or' plate being free,and this plate is arranged to move in such a manner as to form agradually-contractin g pocket, first with the top A and then with thebottom A or vice versa. In this movement the plate preferably alwaysremains at a right angle to the central longitudinal plane of theconduit A. The movement may be described as an oscillation about ashifting center, and as aninstance of the many devices which mechanicalskill and ingenuity may contrive for this purpose I have shown a Web B,extending centrally from the plate B into the chamber A where said webis pivotally connected, as at 0 with a crank-disk O or equivalent parton a shaft 0, to which motion may be imparted by a pulley C Verticallyabove the shaft 0 a stationary guide-pin A is projected across thechamber A and this pin engages the web B at the edges of a slot B thepin 0 being in the continuation of the slots axis.

The operation is as follows: Starting from the initial position shown inFigs. 1, 2, and 3, if the shaft is rotated in the direction indicated bythe arrow in Fig. 1 the plate 13 will first be rocked on the pin A so asto bring the right-hand end of the plate down into the position shown inFig. 4, while the left-hand end of the plate remains practicallystationary in its upper position. This will obviously cause a pressureon the lower face of the plate, causing the fluid or other medium to beforced toward the left, and above the plate a suction will be producedto draw in a fresh supply of the medium and impart to it an impulse inthe same direction. The position shown in Fig. 4 is obtainedapproximately after a quarter-revolution of the shaft O. As the pin Cnears its lowest position the right-hand end of the plate B remainsstationary and its left-hand end swings down, so as to finally lie closeto the bottom A as indicated in Fig. 5. In passing from the positionshown in Fig. 4 to that illustrated by Fig. 5 the flaring pocket formedbetween the plate B and the bottom A is contracted gradually, thusforcibly expelling the fluid from said pocket toward the left. At thesame time the suction between the upper face of the plate B and the topA of the conduit A continues. During the further rotation of the shaft Cthe right-hand end of the plate B rises to the position shown in Fig. 6,and finally the plate returns to the original position shown in Fig. 1,forming first a flaring pocket with the top A and then graduallycontracting said pocket to continue the n10- tion of the fluid in thesame direction as before. If the shaft C is rotated in the oppositedirection, the order of positions is simply reversedthat is, the plate Bwill pass successively through the positions shown in Figs. 1, 6, 5, 4,and 3, and of course the fluid or other medium will be propelled in theopposite direction through the conduit A.

The employment of the apparatus above described as a pump will beobvious. The attachment of suitable suction and delivery pipes to theends of the conduit A is merely a matter of mechanical skill. This pumpis reversible by simply reversing the shaft 0. The apparatus whenworking in air may be used as an air-pump or as a ventilator or blowerfor the va1'iotis, purposes for which such devices are used. If theconduit A is attached to the hull of a ship or toa suitable part of anair-ship, the mechanism will form an efficient propeller if placed inthe longitudinal axis of the vessel or parallel thereto, while whendisposed at an angle to such axis the mechanism will constitute apowerful steering device. My invention is applicable to the propulsionor compression or exhaustion of fluids, gaseous and liquid, and may alsobe made to operate on solid or semisolid material, such as powderedsubstances and heavy sticky juices or the like. Further, the mechanismmay be used as a washing-machine, as it will exert an intermittentpressure on the clothes at difierent points and will automatically feedthe clothes through the channel or conduit A. The mechanism may also beemployed as a machine for kneading dough.

Another form of my invention is shown in Figs. 7 to 11. Here I arrangetwo superposed plates B B in the conduitA between the top A and thebottom A thereof and provide duplicate mechanism for imparting to thesaid pressure-exerting members the motion illustrated by Figs. 7 to 10.The webs B may in this case be arranged at the sides instead ofcentrally and worked by oppositely-projected cranks C on the shaft C;but the throw of each crank is only about one-half the height of theconduit A. From the position shown in Fig. 7 the right-hand ends of thetwo plates first swing together to form a tapering pocket, as in Fig. 8.Then the left-hand ends of the plates move toward each other to reachthe position shown in Fig.9. Thereupon the righthand ends separate, asin Fig. 10, and finally the left-hand ends separate and return to theposition shown in Fig. 7. This succession of movements obviouslyproduces a suction at the right-hand end of the conduit and a deliveryaction at the left-hand end, as indicated by the arrows. If the shaft 0'is rotated in the opposite direction, the fluid will travel from left toright.

With a construction comprising two movable plates, as in Figs. 7 to 11,the conduit A, or at least the top A and bottom A thereof, may beomitted, although the action will be more powerful if a complete conduitis used. While it is true the two plates B B form a pocket with eachother and may therefore exert a pressure and propelling action withoutthe cooperation of the conduit-walls, two additional pockets are formedwhen the conduit-walls A A are provided and the efficiency isconsiderably increased.

In Fig. 12, A indicates a conduit extending lengthwise of a marinevessel below the waterline, said conduit being normally open at bothends, so that it is filled with water. In said conduit is arranged thetransversely-movable pressure exerting or propelling plate B, whichreceives motion by means of pistons D D, working in cylindersE E, andconnected with said plate by piston-rods F F. In order to properlygovern the admission of the motive fluid to the driving-cylinders E E,so that the plate B will have the motion hereinbefore described withreference to Figs. 1 to 6, I provide valves G G, of which the valve Gmay be the inlet-valve for the cylinder E, while the valve G is theoutlet-valve for the cylinder E. These two valves are worked by a leverH, fulcrumed at H and connected with the piston-rod F. Thus thepiston-rod F controls the inlet-valve of one cylinder and theoutlet-valve of the other cylinder. Similarly, the piston-rod F willthrough the medium of a lever 11 control the inlet-valve of the cylinderE and the outlet-valve of the cylinder E. These two valves are not shownin the drawings; but it will be understood that they correspond exactlyin construction to the valves G G. In order to facilitate the making ofrepairs, I may provide gates I with suitable raising and loweringmechanism J, so that the part of the conduit A which contains thepressure-exerting plate B may be ICC separated from the outer portionsof the conduit. Upon then removing a section of the conduit between thetwo gates I the plate B becomes readily accessible. Gates of thischaracter may also be provided with the constructions shown in Figs. 1,2, and 11.

In each of the constructions hereinbefore described the movement of thepressure-exerting plate forces the water or other medium against arelatively solid surface or resistance, which may be formed bythestationary wall of a conduit, by the hull of a vessel, or by anotherpressure-exerting plate. I wish to state, however, that if a propellingor pressure-exerting plate is given a movement of the characterdescribed it will exert a propelling action even if there is no solidresistance cooperating with it, as the relatively stationary body ofwater or other fluid will form a sufficient resistance to obtain auseful result. It is preferable, however, that the device should consistof two cooperating members extending longitudinally of the direction inwhich pressure is to be exerted, the said members having free ends andbeing combined with mechanism for separating them first at one end andthen at the other and then again bringing them together in the samesuccession. This relative movement may be effected by moving bothmembers or only one of them. Having thus described my invention, I claimas new and desire to secure by Letters Patent-- 1. The combination of apipe or conduit having an inlet and an outlet, a pressure-exertingmember movable transversely in said conduit, a web extending from saidmember in a plane substantially parallel to the longitudinal centralplane of the conduit, said web being provided with a transverseguideway, a stationary guide engaging said guideway and a rotary shafthaving an eccentric pivotal connection with said Web, the point ofpivotal connection being situated in the continuation of the guideway.

2. The combination of two plates movable toward each other into closeproximity and also movable away from each other at both ends to form apocket between them, and mechanism for causing said plates to firstapproach each other at one end and then at the other end, and thereuponto recede from each other first at that end at which they firstapproached each other, and then at the other end.

3'. The combination of a pipe or conduit having an inlet and an outlet,two pressureexerting plates extending lengthwise of the conduit in thesame portion thereof, said plates being movable transversely toward andfrom each other, and also relatively to the walls of the conduit, andmeans for causing said plates to move together and then separatealternately at opposite ends.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
